How can removing water change the color of a substance? Lab partners remove the water of crystallization from hydrated copper (II) sulfate, record their observations, then rehydrate the solid. The resource is printable and contains ideas...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...

Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Students grow crystals and document their observations by recording timeing and growth. Additional characteristics of crystals are observed under a black light, by growing under different conditions and mineral content is determined.

After a concise introduction to the water cycle, junior meteorologists access NOAA's average snowfall data. They choose a city to examine in terms of precipitation. Then they look at historical snowfall data and use it to predict snow...

Some fish contain proteins that act like antifreeze in order for them to live in the frigid waters of Antarctica! High schoolers determine how much antifreeze a fish needs to lower its body temp to -2.5 degrees. Teachers act as a...

This isn't just an art lesson, it's a science lesson too. Kids draw a lovely winter scene and then paint over it with a solution of epsom salts and water. They make predictions, then observe how crystals form as the water evaporates...

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

Candy is one of my favorite words, and it's an even better word when it relates to science. Yes, candy science can happen when you grow rock candy crystals with your class. The entire process for growing these edible wonders of nature is...

Crystallize the answer to the question that has been investigated since the first of four lessons: What is the unknown crystal? Pupils have examined, crushed, and dissolved four samples plus an unknown as an exploration of the properties...

Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

How does hydrogen bonding explain ice crystals? An engaging interactive answers just that. Scholars explore how polar molecules interact and observe the changes as temperature fluctuates as well as the hydrogen bond attraction.

Water may appear to be crystal clear, but there could be dissolved substances present. Lab groups make a one-part-per-million of a food coloring solution to demonstrate this concept. As part of an outstanding unit about water, this...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Does the crystal structure of a hydrated solid determine the proportion of water absorbed, or does the application of heat change the absorption? Scholars experiment with both variables to determine the answer. They add their collected...
